The 4th International Conference on Metal Cutting, Special Processing and Machining Automation was held in Beijing from April 25 to April 1989. At the conference a total of more than 140 papers from more than a dozen different countries and regions were published. Now these papers are described below. (The brackets are the names, region names and foreign names of our country.) Papers on cutting theories include: Using sliding field theory to study the metal cutting model (Guangdong); A new method to evaluate the cutting process in case of tool breakage (Harbin); Relationship between material anisotropy and shearing angle in right angle cutting (Hong Kong); Stress distribution in plane of chip flow in bevel cutting tool
